Bump PORTREVISIONs for ports depending on the canonical version of GCC and
lang/gcc which have moved from GCC 4.9.4 to GCC 5.4 (at least under some
circumstances such as versions of FreeBSD or platforms).
This includes ports
- with USE_GCC=yes or USE_GCC=any,
- with USES=fortran,
- using using Mk/bsd.octave.mk which in turn has USES=fortran, and
- with USES=compiler specifying openmp, nestedfct, c++11-lib, c++14-lang,
c++11-lang, c++0x, c11, or gcc-c++11-lib.

Update USE_GITHUB so it does not require GH_COMMIT.
Using this new scheme allows only setting the _tag_ or _commit hash_ in
GH_TAGNAME and not having to know the hash for a tag. This scheme will
download a tarball that has a different checksum than before due to a changed
directory name for extraction.
The following MASTER_SITES are provided to retain the old checksum and
directory structure (that require GH_COMMIT):
GH -> GHL
GITHUB -> GITHUB_LEGACY
